One comment - never denigrate newbies for their lack of knowledge. It's rude on a human level and none of us were born with this knowledge. Be polite and help them grow their knowledge and gain a deeper appreciation of the sport you like so much.
After finally getting the drive to go the track and all that that would entail the first time, (hours in car lines, parking a mile away, baking in the sun, massive crowds, long distances to walk, expensive track food, restroom lines, sunburn, dehydration, etc.) the last thing you want after all that effort of attending a national event is to be embarrassed in front of your friends by an intolerant cognoscenti.
Some empathy for new fans is suggested. You might tip the balance in favor of them coming back!
